Letters Patent No. 92,728, dated July 201869.

IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to these Letters Patent and making part of the same.

To all whom it may concern:

- Be it known that I, JOHN B. JOHNSON, of Rock Island, in the county of Rock Island, and State of Illinois, have invented certain new and useful Improvements in a Corn-Planter; and I do hereby declare that .the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specitication, and to the letters of referenccmarked thereon, like letter. indicating like parts wherever they occur.

' To enable others skilled in the art to construct and use myyinvention, I will proceed to describe it.

Thisinvention relates to corn-planters fand It consists in the combination of foot-levers or treadles, with a rock-shaft and arms, 'connected with the seed-slides in such manner that said slides may be operated by the pressure of the drivers feet upon the treadl'es. l

Also, in the construction and arrangement ofl theA seed-slides, and in the manner of attaching the seedhoppers. v f

Figure 1 is a vertical cross-section of` the machine, on the line :v-a of fig; 2.

Figure 2, a longitudinal vertical section on the line y y ot'g; and

Figure 3, atop-plan view of the machine.

The machine consists of a frame mounted upon two parallel runners, which runners open the furrows, and have the seed dropped through their heels into the furrow, Y the runners having mounted directlyupon them, at their rear ends, seed-hoppers, provided with seed-slides, to feed the corn, the said .slides being operated by arms extending down from a rock-shaft,

provided with arms, connectedby chains with trcadles in sucha manner that the pressure of the feet alternately upon one andthe other of the treadles .will cause the corn to be dropped, a hill through each runner, and which is covered by arms or blades following in the rear of each runner.

a a represent the frame of the machine, connecting the two runners b l1, and having attached to its rear endsl two blades my, one of which extends down behind each runner, and are for the purpose of `tilling in the earth over the seed, after it is deposited in the furrow.

On the upper side of each of the runners, at the rear end, I mount a seedhoppei,.n, and provide them at their bottoms with plates j, held in place l,by lugs p, formed on the runners, and fitting into holes in the plate, as shown.

rIlhese platesl are provided with two holen or cells, L and lt', through which the seed is fed.

The plates j do not ll the entire bottom of the hoppers, but leave a space on one side, ruiming lengthwise Ot'the'machine, as shown.

.This space is filled by a reciprocating bar or slide, g, of the same thickness as the plate j, and being flush therewith at top and bottom, as shown in g. l, the

bar or slide extending out under the edge of the hopper, and projecting some distance forward, and having a slot in its front end, as shown.

To this bar I secure three arms, t, u, and h, one lying across on top of the plate j, and two close against it, on the under side, and all ybeing for the purpose of shutting over the mouths of the seed-cells k and lf',`

I and regulating the flow of seed.

The two arms h and t, on the under side of the slide g, are situated a short distance apart, and the upper arm 1l, Icated opposite the opening between them, as shown in figs. 2 and 3.

On each runner, just forward of its hopper, is a standard, w, the two being in line, and inthcse standards is-mounted a horizontal rock-shaft, cl, having secured, near each end, a pendent arm, j, which passes down through the slotted ends of the slides y.

This shaft has alsosecured to it, near its middle, two arms cl", horizontal, or nearly so, and extending out on'opposite sides of the shaft, and each connected by a cord or chain with one of ythe treadles c, which arev hinged to the front end of the frame, and extend v back to near the rear of the machine, and in position such as to'be conveniently operated by the feet of the driver, so that 4as oneV or the other of the treadles is operated, the rock-shaft will be caused to turn, and

through the medium of thearms j, operate thev slides g, and thus drop the seed. f

The relation of the arms h u t are to one another, and to the cells k le such, that the cells are alternately closed at top and bottom, so as to receive a charge or hill of seed from the top, and then, at the reverse movement of the slide, discharge it at the bottom, down through the .runner into the furrow.

The machine drops at each impulse of the slide, not requiring the motion forward and back, as in many others. v

On the standards w, which support the rock-shaft, v

but above said shaft, is mounted a rod or' bar, ll', for the driver to hold by, to sustain, or steady himself, the

bar being capable of adjustment up or down, and back distance apart.

rlhe draught-poles of the machine is placed at the middle of the frame, and extends back to the rear crossbar, and being placed high up, forms a guide-bar for the driver in planting.

The hoppers 'n are secured in place byearso, which lo'ck down over horizontal flanges formed on the outside of the runner at their top, as shown in fig. 1. The rear ends of the runner are made very low, and

thus the seed-slides located suciently near the earth to drop the seed directly from the slide into the'furrow, and thus dispense with the flipper-valve, or double drop, commonly'used.

By this mode ,of constructing the machine, I am enabled to produce a very cheap and efdcient machine.

Having thus described my invention, What I claim, is-' 1. The slide g, having the plates h, t, and u, attached thereto, and arranged to operate in connection with the plate j, substantially as herein described.

2. The combination of the treadles c, rock-shaft d,

with the arms d', and pendants or levers f attached, and the seed-slides g, all arranged to operate as herein set forth.

3. The combination of the removable plate j, held in position by the lugs p, and the detachable hoppers n, secured bythe hooks o, whereby all the parts may be readily det-ached or replaced, as set forth.V
